HOMOGEN'IZER.

Application filed January 1-5, 1920. Serial No. 351,669.

To all whom it may concern:

Be it known that I, OSCAR A. WENBERG, a citizen of the United States, residing at Batavia, in the county of Kane and Stateof Illinois, have invented a new and useful Improvement in Homogenizers, of which the following is a specification.

This invention relates to homogenizers for internal combustion engines.

An object of this. invention is to thoroughly mix the air and fuel in the intake pipe or manifold after they have passed the carbureter. It is particularly useful on engines burning low-grade gasoline or other fuels which do not volatilize readily.

This and other objects are accomplished by my invention which is fully described in the following specification and shown in the accompanying drawings in which Figure 1 is a partial front elevation of an automobile engine having my invention applied to the intake manifold and shown in section, and Fig. 2 is a section on the line 2-2 of Fig. 1.

I have illustrated as an embodiment of my invention an automobile engine having a cylinder pocket 10 which is shown in front elevation in Fig. 1. This has an ex haust manifold 11 and an intake manifold 12 secured thereto in such a way that the intake manifold lays along the side of the exhaust manifold, but is somewhat separate therefrom. The intake manifold 12 has an inlet passage 13 integrally connected therewith which opens into a mixing chamber C. Secured to this is an inlet tube 15 which has an enlarged portion 16 secured to the inlet manifold.

At the lower end of the intake pipe 15 is secured any desired form of carburetor 17. Between the inlet members 13 and 16 within the enlarged chamber G are placed bafiie plates 18 and 19. The lower baflie plate 18 is semi-spherical in shape and has a series of peripheral holes or slots 20 near its upper edge, leading from the enlarged chamber A to the intermediate chamber B. A small hole 21 is also placed at the bottom of this baffle plate. The upper baflie plate 19 has a relatively large central opening 22, which is on the opposite side of the chamber C fromthe passage 13 and preferably in axial alignment therewith.

around the lower bafile 18 into the enlarged chamber A and is forced with considerable velocity through the openings 20 into the intermediate chamber B. A drop in pressure also occurs after passing this opening. This drop in pressure, together with the violent churning of the air and fuel at this point drives off by vaporization most of the liquid fuel which is held in suspension. The mixture now passes through the opening 22 into the mixing chamber C where an additional whirling and mixing process takes place. The mixture then passes up through the tube 13 striking the back wall nearest the exhaust manifold and is distributed through the manifold -12 to the cylinders.

Owing to the proximity of the inlet manifold 12 to the exhaust manifold 11 the inlet manifold is heated and any liquid fuel which is deposited upon its surface is vaporized and taken up by the air and carried to the cylinder.

In order to prevent the formation of a pocket for catching any condensed fuel, the baflle plate 18 is provided with a hole 21 which serves to drain back to the carburetor any liquid fuel which may be condensed upon the walls of the inlet passage.

While I have shown and described but a single embodiment of my invention, itis to be understood that it is capable of many modifications. Changes therefore in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as possible in view of the prior art.

What I claim as new and desire to secure by Letters Patent is:

1. In combination, an intake passage for a mixture of air and liquid fuel, said passage comprising an enlarged chamber, the,

intake end flaring smoothly into said cham her, and a transverse partition therein extending across said chamber and having a centrally arranged hole through which all of said mixture must pass.

2. In combination, an intake passage for a mixture of air and liquid fuel, said passage comprising an enlarged chamber, the intake end flaring'smoothly into said chamber, and a transverse partition therein extending across said chamber and having a centrally arranged hole through which all of said mixture must pass, said partition being convexly arched toward the intake side.
